Systems configured to manage cryptocurrency wallets having cost basis tracking and methods of use thereof

ABSTRACT

Cryptocurrency can be stored in a plurality of cryptocurrency wallets associated with a plurality of respective users and managed by establishing a unit cost basis value for each cryptocurrency unit in a fiat currency. For example, a purchase request is received by a server computer from a user device. The purchase request is associated with a merchant to be paid in a cryptocurrency chosen by a user and stored in a cryptocurrency wallet of the user. A cryptocurrency exchange from multiple cryptocurrency exchanges having the best cryptocurrency exchange rate is identified for converting the chosen cryptocurrency to the fiat currency. A gain for the purchase transaction is calculated when the best cryptocurrency exchange rate is greater than the unit cost basis value of the chosen cryptocurrency stored in the cryptocurrency wallet of the user. The fiat currency converted in the identified cryptocurrency exchange is received from the cryptocurrency exchange to pay the merchant.

In some embodiments, events and/or actions in accordance with the present disclosure can be in real-time and/or based on a predetermined periodicity of at least one of: nanosecond, several nanoseconds, millisecond, several milliseconds, second, several seconds, minute, several minutes, hourly, several hours, daily, several days, weekly, monthly, etc.

As used herein, the term “runtime” corresponds to any behavior that is dynamically determined during an execution of a software application or at least a portion of software application.

Cryptocurrency may be purchased and/or transferred into cryptocurrency wallets for storage. The cryptocurrency wallets may be configured to hold private and public authentication keys, for example, for the cryptocurrency stored in the wallet. When a user of cryptocurrency desires to use the cryptocurrency stored in a wallet of the user, either through a cryptocurrency transfer to another user, or a sale of cryptocurrency during a merchant purchase, the user typically sends information over a communication network to a recipient (e.g., another user or a cryptocurrency exchange) with at least a public key and the number of cryptocurrency units associated with a cryptocurrency type, such as Bitcoin, Ethereum, Ripple, for example, held in the wallet.

This information may be used to record the transfer of the cryptocurrency units from the sender to the recipient onto a blockchain ledger tracking the ownership of the cryptocurrency units of a particular type in-circulation. In addition to the information sent to the recipient, the private key of the user may be used in the transaction to digitally authenticate ownership of the cryptocurrency by the user before recording the ownership transfer transaction of the cryptocurrency units on the blockchain ledger.

Typically, the transfer and/or use of cryptocurrency in purchase transactions of goods and/or services may occur without any prior knowledge as to how much the user paid in fiat currency (e.g., U.S. Dollars, euros, Swiss francs, etc.) for the cryptocurrency and/or the value of the cryptocurrency in fiat currency at the time that the cryptocurrency was transferred to the user's wallet. Thus, the cost basis for every cryptocurrency acquisition by the user is typically not established, nor electronically recorded in a respective blockchain and/or in an off-blockchain database. Furthermore, the value of any type of cryptocurrency relative to any fiat currency is market-based, and thus, the value may fluctuate at any instant. Thus, a loss or a gain in value of any cryptocurrency relative to a fiat currency may occur at any instant which requires considerable computing resources to track such potentially instantaneous fluctuations.

Different governmental agencies worldwide now view the use of cryptocurrency in any transaction as a taxable event. When a user, for example, uses cryptocurrency to purchase goods and/or services in purchase transactions, the gain for that transaction may be defined as the value of the cryptocurrency units in fiat currency used to pay the merchant when the cryptocurrency units relative to the value of the same cryptocurrency units in fiat currency at the time of the user's acquisition. The gain in each purchase transaction may be used to determine a tax payment amount owed to the tax authority for every purchase transaction that cryptocurrency may be used to pay for the goods and/or services.

In some embodiments, the present disclosure herein provides for managing cryptocurrency wallets having cost basis tracking and uses thereof. At least one technical solution that the illustrative inventive systems and methods of the present disclosure provide is based on maintaining a cost basis for every type of cryptocurrency and its correspondence to a number of cryptocurrency units stored in the user's cryptocurrency wallet, which is needed for accessing the tax payment amount owed to the tax authorities for every purchase transaction that cryptocurrency is used by the user to pay for the goods and/or services.

Furthermore, in at least some embodiments, the illustrative inventive systems are configured to assist the user and/or tax preparer in tax reporting to the tax authority by maintaining the tax payment amount owed for every purchase transaction using cryptocurrency stored in the user's cryptocurrency wallet. Additionally, and/or optionally, in at least some embodiments, the illustrative inventive systems are configured to directly pay the tax payment amount owed by the user to the tax authority for every purchase transaction using cryptocurrency stored in the user's cryptocurrency wallet.

FIG. 1 depicts an exemplary inventive system 100 for managing cryptocurrency wallets having cost basis tracking and uses thereof, in accordance with one or more embodiments of the present disclosure. System 100 may include a server computer 105 of a financial institution or entity, multiple servers 157 of respective multiple cryptocurrency exchanges 156, at least one user device 185 of at least one respective user 175 from a plurality of users at a point-of-sale (POS) terminal 165 of a merchant, a computer terminal 171 with a webpage managed by the merchant, a server 168 of the merchant, and a server 162 of a tax authority, all communicating 135 over a communication network 170. User device 185 may include a smartphone, a cellphone, a tablet, and the like.

In some embodiments, server computer 105 may include a processor 110, input/output devices 125, communication circuitry and interface 130 to enable server computer 105 to communicate 135 over communication network 170, and a memory 140.

Processor 110 may execute software modules stored for example in memory 140. The software modules may include a cryptocurrency wallet management module 112, a best cryptocurrency exchange price assessment module 114, a cost basis tracking module 116, tax computation and reporting module 118, and a graphic user interface (GUI) module 120. Memory 140 may store a number of databases, which may include a database 145 of cryptocurrency wallets 150 and a secondary accounts database 155 with user accounts 160.

In some embodiments, cryptocurrency wallet database 145 may include a digital cryptographic wallet for a plurality of users, each user wallet denoted as user1, user2, . . . and usern. There may be n users where n is an integer. Each user wallet may include not only the cryptographic credentials (unique public and private keys) and the cryptocurrency portfolio (e.g., at least one cryptocurrency type and number of cryptocurrency units for each type) for each user, but also cost basis data for each cryptocurrency stored in each user wallet which may be managed by cryptocurrency wallet management module 112.

In some embodiments, input/output devices 125 may include a plurality of electronic ports such as USB ports, for example, for coupling cryptocurrency hardware wallets to server computer 105. Cryptocurrency hardware wallets may be used to store the cryptographic credentials (unique public and private keys) and the cryptocurrency portfolio (e.g., at least one cryptocurrency type and a number of units for each type) for some users in the plurality of users. However, the cost basis data for each hardware wallet may be stored in parallel, in cryptocurrency wallet database 145 in an associated wallet file 150.

In some embodiments, secondary accounts database 155 may include a plurality of user accounts 160 for each of n users denoted user1, user2, . . . and usern. Each user account 160 may be used to store tax payment information for every purchase transaction by a user using cryptocurrency stored in respective user cryptocurrency wallet 150.

In some embodiments, user 175 may desire to perform a purchase transaction with a merchant. User 175 may be located, for example, in a store of the merchant, finds merchandise to buy, and goes to checkout counter with POS terminal 165. User 175 may scan the items into POS terminal 165. Alternatively, the agent may scan the merchandise at the checkout counter into POS terminal 165. After recording the items for sale in POS terminal 165 in a fiat currency, such as U.S. dollars, for example, the agent may ask user 175 how the user wishes to pay for the merchandise. The user may indicate to the agent that he wishes to pay using cryptocurrency.

In some embodiments, a cryptocurrency wallet management application running on user device 185 (e.g., a processor of user device 185) may use a graphical user interface (GUI) 180 to display cryptocurrency transaction information on a screen of user device 185. Processor 110 through GUI purchase manager module 120 may remotely control user device 185 over communication network 170 and control the cryptocurrency transaction information displayed on GUI 180. In other embodiments, cryptocurrency wallet management module 112 may be executed by a local processor on user device 185, but still communicates, in part with the cryptocurrency wallets in memory 140.

In some embodiments, the fiat currency type may be country or region-dependent. In some embodiments, the fiat currency may be detected from the user's location (e.g., location of user device 185) automatically by location tracking, such as using global positioning systems (GPS), for example. In other embodiments, the fiat currency may be preset in the application by the user.

In some embodiments, when the user may indicate to the POS terminal and/or to an agent that the payment is to be in cryptocurrency, a barcode such as a QR code 167 may then be displayed on a display of POS terminal 165 with information about the purchase transaction. User 175 may use a barcode application (e.g., QR scan application) or a scan function in the cryptocurrency wallet management application running on user device 185 to initiate communication with cryptocurrency wallet management module 112 on server computer 105.

In some embodiments, user 175 may use an imaging device such as a camera running on user device 185 to scan the barcode which causes the processor on user device 185 through the cryptocurrency wallet management application to display the purchase price of the items in fiat currency and the name of the merchant on graphical user interface (GUI) 180.

In some embodiments, user device 185 may pair 186 with POS terminal 165 using Bluetooth, for example, which causes the processor on user device 185 through the cryptocurrency wallet management application to display the purchase price of the items in fiat currency and the name of the merchant on graphical user interface (GUI) 180.

In some embodiments, user 175 may operate a webpage displaying the merchandise of the merchant either locally in the merchant's store or remotely at home. After checkout, user 175 may click on a link 172 on the display of computer terminal 171, which causes the processor (e.g., through cloud computing, for example) on user device 185 through the cryptocurrency wallet management application to display the purchase price of the items in fiat currency and the name of the merchant on graphical user interface (GUI) 180.

Cryptocurrency wallet management module 112 and/or GUI purchase manager module 120 may then cause the cryptocurrency portfolio held in a wallet 150 of user 175 to be displayed on GUI 180 via communication network 170. In various embodiments, GUI 180 may allow user 175 to view the purchase price in the fiat currency and in all of the available cryptocurrencies held in wallet 150. Representative exchange rates from online databases may be used for converting purchase price in fiat currency for all of the available cryptocurrencies held in wallet 150 to a purchase transaction-related number of cryptocurrency units.

Cost basis module 116 and tax computation module 118 may then be used to cause GUI 180 to display an estimated tax payment amount value due for each of the available cryptocurrencies held in wallet 150 to pay for the purchase transaction. In some embodiments, tax computation module 118 may apply representative exchange rates from online databases for converting purchase price in fiat currency for each cryptocurrency to a purchase transaction-related number of cryptocurrency units. In other embodiments, best cryptocurrency exchange module 114 may query multiple cryptocurrency exchanges 156 to receive the best cryptocurrency exchange rates for each of the cryptocurrency types held in wallet 150 of user 175 for tax computation module 118 to compute a more accurate estimate tax payment amount value due using each of the possible cryptocurrencies in the user's wallet.

User 175 may then choose, using GUI 180, which cryptocurrency to use to pay for the purchase transaction. User 175 may also choose whether to add additional cryptocurrency funds to the purchase transaction to cover the tax payment amount value due to the tax authority. Processor 110 using best cryptocurrency exchange module 114 may communicate in real-time with multiple cryptocurrency exchange servers 157 of multiple cryptocurrency exchanges 156 to identify which cryptocurrency exchange has the best cryptocurrency exchange rate. Cryptocurrency wallet management module 112 may then compute a cryptocurrency purchase amount based on the fiat purchase amount of the purchase transaction and the best cryptocurrency exchange rate.

In some embodiments, cryptocurrency wallet management module 112 on server computer 105 (e.g., backend server) may compute a purchase transaction-related number of cryptocurrency units of the chosen cryptocurrency from the fiat currency amount. Cryptocurrency wallet management module 112 may deduct the number of cryptocurrency units from wallet 150 of user 175 needed to pay for the purchase transaction, and may communicate 135 or relay the deducted cryptocurrency along with the user's digital credentials associated with the user's cryptocurrency wallet to the identified cryptocurrency exchange with the best cryptocurrency exchange rate. In response, the identified cryptocurrency exchange may exchange the purchase transaction-related number of cryptocurrency units of the chosen cryptocurrency to fiat currency and may relay the exchanged fiat currency to server computer 105.

In some embodiments, user 175 may decide to sell one or multiple cryptocurrencies held in wallet 150 in a batch to pay for the purchase transaction in the fiat currency immediately or over a short time period.

In some embodiments, upon receipt of the fiat currency, cryptocurrency wallet management module 112 may send a confirmation to user device 175, POS terminal 165, and the merchant (e.g., to merchant server 168) that the transaction was executed. Cryptocurrency wallet management module 112 and/or tax computation and reporting module 118 may split the received fiat currency. A first part of the received fiat currency may be sent over a payment gateway to pay the merchant (e.g., transfer the first part to an account of the merchant), and a second part may be transferred to secondary account 160 associated with user 175 to pay the tax payment amount value due to the tax authority for the cryptocurrency-based purchase transaction.

In some embodiments, a third portion of the received fiat currency may be sent to a gateway account (e.g., a gateway service fee) of the financial institution or entity for the use of the service. The service fee may be used to fund rewards for customers similar to credit card points, for example.

FIG. 2A depicts a first exemplary graphic user interface 200 for managing a cryptocurrency storage request, in accordance with one or more embodiments of the present disclosure. GUI 200 may be controlled by cost basis tracking module 116. GUI 200 may be displayed on the display of user device 180 of user 175 for managing deposits of cryptocurrency into wallet 150 of user 175. GUI 200 may be displayed on a private computer of user 175 with an application running thereon for communicating with cryptocurrency wallet management module 112 and/or cost basis tracking module 116. The embodiments for computing the tax payment amount value to pay for the tax due from paying the purchase transaction in the chosen cryptocurrency held in wallet 150 depends on the accurate cost basis tracking of the stored cryptocurrency.

In some embodiments, to ensure accurate cost basis tracking of each cryptocurrency deposit stored in the wallet, GUI 200 may request that the user enter the cost basis data prior to receiving the cryptocurrency for storage. GUI 200 may prompt the user to enter the cryptocurrency type 202, a number 204 of cryptocurrency units, a date 206 the cryptocurrency was purchased with fiat currency, a fiat currency 210, and a value 208 of the purchase of the cryptocurrency in fiat currency 210. In other embodiments, a second embodiment of GUI 200 (not shown) may manage the case where the cryptocurrency was transferred to the user, but not purchased directly from fiat currency. In this case, GUI 200 may request the date of receipt of the cryptocurrency from the sender, the reasons for exchange of the cryptocurrency, and any needed historical exchange rate data may be queried from cryptocurrency databases to establish a cost basis relative to a desired fiat currency.

In some embodiments, the cost basis data may already be known by server 105 if the purchase was made previously through the same app running on user device 180 communicatively coupled 135 to server 105.

In some embodiments, the cost basis data may be retrieved from cryptocurrency exchange 156 that performed the purchase transaction of fiat currency,

FIG. 2B depicts a second exemplary graphic user interface 215 for managing a cryptocurrency storage request, in accordance with one or more embodiments of the present disclosure. Once this cost basis information is entered into GUI 200, cost basis tracking module 116 may approve the request to receive the cryptocurrency transfer for storage in wallet 150 of user 175. A GUI 215 may be displayed on user device 185 or on a private computer of user 175 also indicates a public key 220 of wallet 150 of user 175 to relay to the sender. In some embodiments, cryptocurrency wallet management module 112 may automatically relay the digital credentials to the sender to send the cryptocurrency for storage in wallet 150 of user 175.

In some embodiments, if the user does not provide adequate cost basis information, cost basis tracking module 116 may reject the request by not relaying the user's digital credentials associated with the user's cryptocurrency wallet. In other embodiments, if the cost basis information is determined not to be accurate, cryptocurrency wallet management module 112 may block the use of the cryptocurrency held in the wallet for merchant purchases as previously described until proper cost basis tracking is restored by the user supplying the necessary information to cryptocurrency wallet management module 112.

In some embodiments, the exemplary DBMS-managed database may be specifically programmed to define each respective schema of each database in the exemplary DBMS, according to a particular database model of the present disclosure which may include a hierarchical model, network model, relational model, object model, or some other suitable organization that may result in one or more applicable data structures that may include fields, records, files, and/or objects. In some embodiments, the exemplary DBMS-managed database may be specifically programmed to include metadata about the data that is stored.

In some embodiments, the exemplary inventive computer-based systems/platforms, the exemplary inventive computer-based devices, and/or the exemplary inventive computer-based components of the present disclosure may be specifically configured to operate in an cloud computing/architecture such as, but not limiting to: infrastructure a service (IaaS), platform as a service (PaaS), and/or software as a service (SaaS). FIGS. 10 and 11 illustrate schematics of exemplary implementations of the cloud computing/architecture(s) in which the exemplary inventive computer-based systems/platforms, the exemplary inventive computer-based devices, and/or the exemplary inventive computer-based components of the present disclosure may be specifically configured to operate.

In some embodiments, the exemplary inventive computer-based systems/platforms, the exemplary inventive computer-based devices, and/or the exemplary inventive computer-based components of the present disclosure may be configured interact and/or to store data in one or more private and/or private-permissioned cryptographically-protected, distributed databases such as, without limitation, a blockchain (distributed ledger technology), Ethereum (Ethereum Foundation, Zug, Switzerland), and/or other similar distributed data management technologies. For example, as utilized herein, the distributed database(s), such as distributed ledgers ensure the integrity of data by generating a chain of data blocks linked together by cryptographic hashes of the data records in the data blocks. For example, a cryptographic hash of at least a portion of data records within a first block, and, in some cases, combined with a portion of data records in previous blocks is used to generate the block address for a new digital identity block succeeding the first block. As an update to the data records stored in the one or more data blocks, a new data block is generated containing respective updated data records and linked to a preceding block with an address based upon a cryptographic hash of at least a portion of the data records in the preceding block. In other words, the linked blocks form a blockchain that inherently includes a traceable sequence of addresses that can be used to track the updates to the data records contained therein. The linked blocks (or blockchain) may be distributed among multiple network nodes within a computer network such that each node may maintain a copy of the blockchain. Malicious network nodes attempting to compromise the integrity of the database must recreate and redistribute the blockchain faster than the honest network nodes, which, in most cases, is computationally infeasible. In other words, data integrity is guaranteed by the virtue of multiple network nodes in a network having a copy of the same blockchain. In some embodiments, as utilized herein, a central trust authority for sensor data management may not be needed to vouch for the integrity of the distributed database hosted by multiple nodes in the network.

In some embodiments, the exemplary distributed blockchain-type ledger implementations of the present disclosure with associated devices may be configured to affect transactions involving Bitcoins and other cryptocurrencies into one another and also into (or between) so-called FIAT money or FIAT currency and vice versa.
